The InterPlanetary File System (IPFS) is a protocol and peer-to-peer network for storing and sharing data in a distributed file system. IPFS uses content-addressing to uniquely identify each file in a global namespace connecting all computing devices.Intro Why IPFS? Explain the original web model and the limitation* Content addressing instead of location addressing* decentralized content distributed among peersContent * Content is hashed as CID* Content is immutable each update generates new CID* Content addressingRouting * Distributed Hash Table (DHTs) maps CID / Peer IP address* DHT server hosts content and DHTPublishing Content * New Content that you want to share on ipfs* hash the content creating new CID* Update your local DHT CID / your ip address* DHT will be updated to all the content peer (NOT the CONTENT)* People searching for your CID will be connected to you and only you.Consuming Content * ipfs client (dht client) want to consume Ipfs://cid/* ipfs client consults its local DHT table to see where this CID is located, gets back a collection of IP addresses* client connects to some or all the peers found hosting that CID* client downloads chunks of the content from each peer so it speeds up* Once the client has the content it is now also updating its local DHT table that it now also hosts that CID (if it supports being a DHT server)* New updated DHT is propogated across peerIPFS Overview (Digrams) Demo More Information Immutable Content* if Content gets updated changes URI how do I inform the user?* hash the public key of the user instead and share thatBrand new Client/server* I know nothing about the network (Bootstraping)* you will be bootstrapped with a collection of ip addresses to start you up.More* IPFS gateway* IP Name server* Solve content* Deleting Content( once other node hosts it no way to delete it from their network)NAT traversalResourceshttps://datatracker.ietf.org/meeting/interim-2020-dinrg-01/materials/slides-interim-2020-dinrg-01-sessa-an-overview-of-the-interplanetary-file-system-ipfs.pdfhttps://www.youtube.com/watch?v=K4Usud4g4iY&feature=youtu.be&t=1008https://twitter.com/hnasr/status/1353548949945163776?s=21https://docs.ipfs.io/conce🎙️Listen to the Backend Engineering Podcasthttps://husseinnasser.com/podcast🏭 Backend Engineering Videoshttps://backend.husseinnasser.com💾 Database Engineering Videoshttps://www.youtube.com/playlist?list=PLQnljOFTspQXjD0HOzN7P2tgzu7scWpl2🏰 Load Balancing and Proxies Videoshttps://www.youtube.com/playlist?list=PLQnljOFTspQVMeBmWI2AhxULWEeo7AaMC🏛️ Software Archtiecture Videoshttps://www.youtube.com/playlist?list=PLQnljOFTspQXNP6mQchJVP3S-3oKGEuw9📩 Messaging Systemshttps://www.youtube.com/playlist?list=PLQnljOFTspQVcumYRWE2w9kVxxIXy_AMoBecome a Memberhttps://www.youtube.com/channel/UC_ML5xP23TOWKUcc-oAE_Eg/joinSupport me on PayPalhttps://bit.ly/33ENps4Join our Thriving Backend Community on Discordhttps://discord.com/invite/CsFbFceStay Awesome,Hussein
